The Comoro thrush (Turdus bewsheri) is a species of bird in the family Turdidae. It is found in the Comoros Islands in the south western Indian Ocean.
The Comoro thrush is a brown bird with olive tinged upperparts, slightly more rufous on the tail and wings. The underparts are whitish except for brown flanks and brown scaling on the breast and belly, central belly and undertail coverts are white. The females are browner than the males but otherwise similar, juveniles are more rufous. The length is 24 centimetres (9.4 in). [3]
The song is a typically thrush-like series of melodious, rich notes which varies between islands. Alarm call is a sharp "twit" and there is a soft contact call. [3]
There are three recognised subspecies, each endemic to a single island. They are: [4]
Comoro thrush occurs in evergreen primary forest and forest edge from sea level to 700 metres (2,300 ft), except for the subspecies T.B. comorensis which occurs on Mount Karthala [4] above this altitude as no forests exist lower than this. [3]
The Comoro thrush normally forages low down in the understorey or on the ground, looking fore spiders, grasshoppers, bugs, molluscs and some fruit and seeds. Will go higher into the canopy to feed on fruit. [5] Sometimes joins mixed species flocks. It breeds in mid-August to October when a cup shaped nest is built from plant fibres and roots, covered in moss and lined with fine grasses. It is placed up to 3 metres (9.8 ft) from the ground on a tree stump, among epiphytes or along a horizontal branch. the normal clutch is 2 eggs. [3]
The Comoro thrush is classified as Near threatened by the IUCN and the main threat is habitat loss through forest degradation due to clearance by subsistence farmers and firewood cutting. [1]
The ring ouzel is a mainly European member of the thrush family Turdidae. It is a medium-sized thrush, 23–24 centimetres (9.1–9.4 in) in length and weighing 90–138 grams (3.2–4.9 oz). The male is predominantly black with a conspicuous white crescent across its breast. Females are browner and duller than males, and young birds may lack the pale chest markings altogether. In all but the northernmost part of its range, this is a high-altitude species, with three races breeding in mountains from Ireland east to Iran. It breeds in open mountain areas with some trees or shrubs, the latter often including heather, conifers, beech, hairy alpenrose or juniper. It is a migratory bird, leaving the breeding areas to winter in southern Europe, North Africa and Turkey, typically in mountains with juniper bushes. The typical clutch is 3–6 brown-flecked pale blue or greenish-blue eggs. They are incubated almost entirely by the female, with hatching normally occurring after 13 days. The altricial, downy chicks fledge in another 14 days and are dependent on their parents for about 12 days after fledging.
The African thrush or West African thrush is a passerine bird in the thrush family Turdidae. It is common in well-wooded areas over much of the western part of sub-Saharan Africa, it was once considered to be conspecific with the olive thrush but that species has now been split further. Populations are resident (non-migratory).
The orange-headed thrush is a bird in the thrush family.
The spectacled thrush, bare-eyed thrush, or yellow-eyed thrush, is a resident breeding bird in the Lesser Antilles and in South America from Colombia and Venezuela south and east to northern Brazil. In Trinidad and Tobago, this thrush is also known as big-eye grieve.
The white-necked thrush is a songbird found in forest and woodland in South America. The taxonomy is potentially confusing, and it sometimes includes the members of the T. assimilis group as subspecies, in which case the "combined species" is referred to as the white-throated thrush. On the contrary, it may be split into two species, the rufous-flanked thrush and the grey-flanked thrush.
The rufous-bellied thrush is a songbird of the thrush family (Turdidae). It occurs in most of east and southeast Brazil from Maranhão south to Rio Grande do Sul states, Bolivia, Paraguay, Uruguay and central regions of Argentina.
The Abyssinian ground thrush is a thrush from the family Turdidae which is native to north-east Africa where it lives at high altitude in montane forests.
The rufous whistler is a species of whistler found in New Caledonia and Australia. Predominantly a reddish-brown and grey bird, it makes up for its subdued plumage with its song-making ability. Like many other members of the Pachycephalidae, it has a variety of musical calls.
The forest thrush is a species of bird in the family Turdidae. It was historically the sole species within the genus Cichlherminia, however the AOU reclassified the species to the genus Turdus in 2009.
The Tristan thrush, also known as the starchy, is a species of bird in the thrush family that is endemic to the British overseas territories of the isolated Tristan da Cunha archipelago in the South Atlantic Ocean.
The Malagasy paradise flycatcher is a species of bird in the family Monarchidae. It is found in Comoros, Madagascar, and Mayotte. Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
The Japanese thrush is a species of bird in the thrush family Turdidae. The species is also known as the grey thrush or the Japanese grey thrush. The species was once split into two subspecies, with birds breeding in China being treated as the subspecies T. c. lateus,, but today differences are attributed to natural variation and the species is treated as being monotypic.
The chestnut-bellied thrush is a species of bird in the family Turdidae. It is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
The great thrush is a species of bird in the family Turdidae. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela. It is considered as the largest thrush in South America. The great thrush's size distinguishes it from the several other uniform slaty-colored thrushes in its range. It inhabits subtropical or tropical moist montane forests and high-altitude shrubland, but can also make use of degraded forest and urban areas.
The red-legged thrush is a species of bird in the family Turdidae. Native to the Caribbean, it is found in the Bahamas, Cayman Islands, Cuba, Dominica, Hispaniola and Puerto Rico. It formerly occurred on the Swan Islands, Honduras, but was extirpated there.
The Ecuadorian thrush is a resident bird found in western South America in western Ecuador and far northwestern Peru. It was formerly considered to be a subspecies of the spectacled thrush, Turdus nudigenis, but has a narrower eyering, and is widely separated in range.
The Tibetan blackbird is a species of bird in the thrush family Turdidae. It is found in the Himalayas from northern Pakistan to southeastern Tibet. Originally described as a separate species by Henry Seebohm in 1881, it was then considered a subspecies of the common blackbird until 2008, when phylogenetic evidence revealed that it was only distantly related to the latter species. It is a relatively large thrush, having an overall length of 23–28 centimetres. Males are blackish-brown all over with darker plumage on the head, breast, wings and tail and dull orange-yellow bills, while females have browner underparts, faint streaking on the throat, and a dull darkish yellow bill. Both sexes may seem slightly hooded. It can be differentiated from the common blackbird by its complete lack of an eye-ring and reduced song.
The rufous-backed robin is a songbird of the thrush family. It is endemic to the Pacific slope of Mexico. It is also known as the rufous-backed thrush.
The Christmas thrush is a subspecies of the island thrush. It is endemic to Christmas Island, an Australian territory in the Indian Ocean.
The Borneo thrush, also known as the mountain blackbird or locally in Dusun as Luhui tana, is a bird in the thrush family. It is a subspecies of the island thrush endemic to the island of Borneo.
